[arm-allstar] Tx and Rx LEDs on GPIO4 &5

Yes this works as an example to USBFOB bits....

Using bit 1 to indicate COS

In simpleusb.conf -

gpio1=out0

in [events] stanza of rpt.conf -

cop,62,GPIO1:1 = c|t|RPT_RXKEYED
cop,62,GPIO1:0 = c|f|RPT_RXKEYED

Using bit 2 to indicate TX

In simpleusb.conf -

gpio2=out0

In rpt.conf [events] stanza -

cop,62,GPIO2:1 = c|t|RPT_TXKEYED
cop,62,GPIO2:0 = c|f|RPT_TXKEYED

Caveats - This only works with Hamvoip code as shown and GPIO3 is reserved
for PTT. You actually do not need TX to an individual bit as you have it in
the form of PTT which could also drive an LED as it is done in many FOBS.
